[Mgs] Oil for Flat-Tappet Engines

[Ed's Shop]

<<It also comes in 20W-50 multi-vis, which is what the GTX I've always run is.>>

Castrol HAS NEW product slowly creeping into stores that DOES have the ZDDP levels out motors need.  Just read the bottle;  says something like "...for older/antigue vehicles ...re-formulated...".  Bottle does NOT (or so they said to begin with) "look" different.  My Machine Shop has it.  You can check this out on their site.
